What is Duo Mobile?

The Duo Mobile app is a free smartphone and tablet application that syncs with your USC 2FA account to provide authentication. 

The app is necessary for the Duo Push authentication method to be applied and can be used to provide passcodes for offline authentication.


Duo Mobile is working with a two-factor authentication service from Duo Security to make logins more secure. For easy, one-tap authentication on your device, the application generates login passcodes and push notifications.

In addition, for other applications and web services that use passcodes, you can use Duo Mobile to handle two-factor authentication. For Duo accounts, you need to activate and connect Duo Mobile to your account before it works.

As part of the Duo enrollment process, you will receive an activation link. You can, at any time, add third-party accounts.


Moreover, it will request access to use your camera for the purpose of scanning QR codes as you activate accounts.

What is Two-Factor Authentication?

Two-factor authentication gives online accounts a second layer of protection. Even if they know your password, checking your identity using a second factor prevents others from logging in to your account.

How It Works

The three steps to stronger authentication are as follows.

  1. Enter the username and password as usual.
  2. Use your phone to verify your identity.
  3. Securely log in.

You're good to go once you've enrolled in Duo. Using your username and password, you can log in as usual, and then use your device to confirm that it is you.
